Well, it is a paradox, Llywydd, isn't it? It is the Conservative Party that argued the most strongly for fiscal powers to be devolved to Wales, and now the argument of the Conservative Party is that, having devolved them, we mustn't use them—that all we can do is to make sure that we don't diverge from what is going on across our border. You can't have it both ways. You either believe, as your party has preached, that powers should be devolved to Wales so that we can make decisions here, or you believe that no difference is possible across the border. We were prepared to sign up to your first proposition.

If the powers are here, the powers must be exercised here. The decisions about which the Member complains are the decisions that this National Assembly made, endorsed in the budget-making process, passing the regulations in January to give rise to them. I'll do what I said in my answer to his first question: having made the decision, we will monitor its effect. If there are lessons to learn, and if there are changes that need to be made, then that's what we will do, but we won't operate on the basis of a series of hypotheticals, where the actual evidence is barely a quarter old.
